Question

what is the best prevention for frostbite?
a wear a wool cap.
b wear a face cover.
c drink hot liquids.
d avoid severe weather.

Explanation:

Frostbite occurs when skin and underlying tissues freeze due to exposure to extreme cold. Wearing a wool cap (A) helps retain heat from the head, which is a significant area of heat loss. A face cover (B) protects facial skin but is more specific. Drinking hot liquids (C) warms the body internally but is not the best overall prevention. Avoiding severe weather (D) is not always practical. Wearing a wool cap is a simple and effective preventive measure as it helps maintain body temperature by reducing heat loss from the head.

Answer:

A. Wear a wool cap.
